STANFORD, Calif. (AP) _ Meghann Shaughnessy clenched her fist after saving match point, then drilled a service ace that propelled her to an upset Tuesday over fifth-seeded Vera Zvonareva at the Bank of the West Classic.
Shaughnessy, a 6-3, 1-6, 7-6 (6) winner, advances to the second round against the winner of a late match between Alexandra Stevenson and Daniela Hantuchova.
"I played three pretty good matches in qualifying and that helped me,'' Shaughnessy said. "She fights hard and it's been a bit back and forth between us.''
Shaughnessy, ranked 69th, beat Zvonareva for the second time in six career meetings and first since the U.S. Open in 2003. Zvonareva won 6-3, 6-3 last week in Cincinnati.
"I always say there's nothing worse than being sent home by the same player in two consecutive tournaments,'' Shaughnessy said. "I'm glad to win if for nothing else to protect my own sanity.''
Shaughnessy is making her seventh consecutive appearance at the event. She beat Venus Williams en route to her only semifinal appearance in 2001, which led to her career-best ranking of 11th.
The 15th-ranked Zvonareva rallied from a 4-2 deficit in the tiebreaker, and eventually took a 6-5 edge by coming to the net.
The ace put Shaughnessy up 7-6. Then Zvonareva hit into the net to end the 2 hour match.
Zvonareva, making her debut at the event, was ranked ninth last August. She's lost her first match in five of the last 11 tournaments since defending her title at Memphis with a straight-sets victory over Shaughnessy.
"We both played well, but maybe she was a little bit lucky on the break points,'' Zvonareva said. ``You play every week, you win, you lose, you go to the next tournament. I just want to be back in the top 10.''
Eighth-seeded Francesca Schiavone took care of Alina Jidkova 6-4, 6-1, Iveta Benesova topped Shuai Peng 6-4, 7-6 (3), lucky loser Sania Mirza beat wild card Eleni Daniilidou 7-6 (4), 2-6, 6-3, and Anna-Lena Groenefeld defeated qualifier Shahar Peer 7-5, 6-1.
The 25-year-old Schiavone, still looking for her first career Tour title, has reached the quarterfinals and semifinals here the previous two years.
Mirza got into the main draw when Chanda Rubin withdrew with a left ankle injury.
